PIPE-FITTING.

SPECIFICATIONforming part of Letters Patent No. 749,309, dated January 12, 1904.

App i filed October 9,1902. Serial No. 126,514. (No model.)

To otZZ whom it may concern:

Be it known that I, PATRICK J. MADDEN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Pipe-Fittings, of which the becomes necessary to dispose that portion of the soil-pipe with which the trap immediately connects in a horizontal or substantially horizontal position, an instance being found in a range of closets having trapped hoppers or bowls. In such a closet all of the bowls are arranged in a row with their outlets presented rearward (usually through a wall or slab) and connected with the substantially horizontal or lateral soil-pipe. This pipe must of course be below the outlet of the trap and usually is supported by floor-plates resting upon the floor. The vent-pipe leads from a point between the seal of the trap and the soil-pipe. Heretofore it has been customary to lead it from a stub on the crown of the trap; but this is open to the objections that it must be carried through the wall or slab. The symmetry and appearance of the fixture are marred and the cost is somewhat increased, the bowl structure being more expensive and requiring better finish than the soil-pipe. Furthermore, it is desirable to make the vent-pipe as direct (uncircuitous) and have it as near vertical as possible, so that air can be readily admitted to the closet branch when the fixture is being discharged to prevent siphoning of the trap being operated or of the traps of the other fixtures connected to the lateral di scharge-pipe. It is also desirable to lead off the noxious gases before they have a chance to enter even the crown of the trap.

The object of the present invention is to provide a pipe-fitting that will be free from or substantially horizontal position, still I desire to have it understood that the invention is not limited to the position in which it is used.

In the accompanying drawings, which is made a part of this specification, Figure 1 is 'a vertical section of a range of closets having a fitting embodying the invention. Fig. 2 is a perspective of the improved fitting. Fig. 3 is a section thereof in a plane which cuts the axis of the lateral branch and is perpendicular to the axis of the main branch.

A represents the bowl or hopper, and B the trap of one of a range of closets. The soilpipe is made up of a number of fittings C. Each of these fittings comprises a main branch D and a bent or offset lateral branch E, which joins the main branch at a point intermediate of its ends and forms the connection between the outlet of the trap and the main branch D, which latter constitutes the soil-pipe proper.

The branch E proceeds from one side of the branch D, and its axis or longitudinal center lies in a plane which is transverse to the said branch D. It has a bend or deflection which sweeps through ninety degrees, so that its terminus is parallel with a tangent of the main branch. In the drawings I have shown the lateral branch as being curved, and while this is preferable still the invention is not limited thereto, but includes any form of bend or deflection that will bring its terminus to substantially the position above described.

Proceeding from the lateral branch, and preferably at right angles to the tangent aforesaid, is a hollow stub F, with which the ventpipe G is connected.

Thus it will be seen that the fitting as a whole has three branches, each of which (considered with respect to an imaginary straight line projected axially through its extremity) is perpendicular to both of the others.

What I claim as new, and desire to secure by Letters Patent, is

1. As a new article of manufacture, a pipefitting having a main branch open at both ends, a lateral branch joining the top of the main branchat a point intermediate of its ends, said lateral branch being disposed with its axis in a vertical plane which is transverse to the axis of the main branch and a stub proceeding laterally from the top of the lateral branch, substantially as described.

2. As a new article of manufacture, a pipefitting having a main branch open at both ends, a bent lateral branch joining the main branch at a point intermediate of its ends and having a portion lying in a plane parallel with a tangent ot' the main branch, and a stub proceeding laterally from the lateral branch, substantially as described.

3. As a new article of manufacture, a pipefitting having a main branch open at both ends, a bent lateral branch joining the main branch at a point intermediate of its ends, said lateral branch having a portion lying parallel with a tangent of the main branch, and a stub proceeding from the lateral branch laterally with respect to said tangent, substantially as described.

&. A pipe-fitting having a main horizontal branch open at both ends, a lateral horizontal branch joining the top of the main branch and lying in a vertical plane which is transverse to the axis of the main branch and a vertical stub proceeding from the top of the lateral branch, substantially as described.

5. In a water-closet, the combination of a bowl having a trap, a horizontal soil-pipe, a connection between the trap and soil-pipe, said connection consisting of a branch which joins the top side of the soilpipe at a point intermediate of its ends and is disposed with its axis in a vertical plane which is transverse to the axis of the soil-pipe and also with the axis of its terminus in a horizontal plane parallel with a tangent of the soil-pipe, and a stub proceeding upward from the top side of said connection, substantially as described.
